Probabilistic Heavy Snow and Icing Discussion
NWS Weather Prediction Center College Park MD
357 PM EDT Wed Oct 17 2018

Valid 00Z Thu Oct 18 2018 - 00Z Sun Oct 21 2018


Day 1...

...Southern and Central Rockies...
A closed low centered over the Southwest is forecast to gradually
weaken and lift out to the northeast into the central Rockies this
period.  This is expected to produce some additional high
elevation snow showers Wednesday night into Thursday from southern
Utah northward into the Wasatch and Uintas, as well as further
east into southern Colorado and northern New Mexico -- namely the
San Juan and Sangre de Cristo mountains.  While widespread heavy
accumulations are not expected, locally heavy totals are possible
across some of the higher peaks.  As the low continues to weaken
and track further east, precipitation is expected to diminish
across the region by early Friday. 

The probability of significant icing (0.25 inches or more) is less
than 10 percent.

Day 2...

The probability of significant snow (4 inches or more) is less
than 10 percent.

The probability of significant icing (0.25 inches or more) is less
than 10 percent.

Day 3...

The probability of significant snow (4 inches or more) is less
than 10 percent.

The probability of significant icing (0.25 inches or more) is less
than 10 percent.
